首先我们需要去deepseek官网去注册deepseek：https://platform.deepseek.com/sign_in

然后我们要创建APIKEY，并配置到系统的环境变量中去。

DeepSeek API使用与OpenAI兼容的API格式，我们需要在OpenAI的API调用格式的基础上，将OpenAI的base_url替换为DeepSeek的endpoint,以及将model替换为DeepSeek的model。其中DeepSeek v3的model名称是：deepseek-chat，

# Please install OpenAI SDK first: `pip3 install openai` import os from openai import OpenAI client = OpenAI( api_key="sk-cf464a9877474ee087fcf20a373bdc66", base_url="https://api.deepseek.com") response = client.chat.completions.create( model="deepseek-chat", messages=[ {"role": "system", "content": "You are a helpful assistant"}, {"role": "user", "content": "Hello"}, ], stream=False ) print(response.choices[0].message.content)
